What is the process of car engine cleaning? How to clean the car engine correctly?

You can go to some professional places to clean it so that you won't damage your engine. It is also possible to pour the cleaning agent into the fuel tank, which must be in a normal proportion. before internal circulation cleaning can be carried out.

You need to clean the oil in the engine before cleaning, and you can directly buy some cleaning liquid and pour it on the engine, and then rinse it with some water, so that it is washed.

You can use a vacuum cleaner, or use a dry rag to clean, pay attention to the cleaning method, understand the cleaning skills, you can use a special detergent to clean.

You can park your car in a place with a drain, cut off the engine cover, clean the oil with a water gun, and then take care of the engine compartment on a daily basis.

Why does a new car always make people feel that the power is enough, and the car that does not do engine cleaning and maintenance on time makes people feel that it is not enough power or fuel-guzzling? This is because engine oil works in a high-temperature environment, which inevitably leads to oxidation and contamination. As a result, after a period of use, the engine will produce carbon deposits, oil stains, and colloids.

Therefore, everyone should clean up the dirt on the engine in time. How to clean the car engine, let me introduce it to you.

Preparation for car engine washing.

Waterproof: Open the engine cover and cover the generator, distributor and brake oil pot with a cloth or seal with a plastic bag.

Takeaway: One point should be covered or sealed. Especially generators and distributors.

Quality standard: Tightly capped or sealed.

How do you clean a car engine?

1) Sprinkle engine cleaner on all parts and spray more on particularly dirty areas.

2) When the engine cleaner begins to dissolve, turn on the high-pressure water spray gun and spray the engine and its dirt.

3) Spray the air outlet under the front windshield with a high-pressure gun.

4) Spray leaves, sludge and dust in the insulated empty chamber between the front windshield and the cabin.

5) Use a high-pressure water gun to rinse the air conditioner condenser water tank, radiator, leaves, mosquitoes, and dust on the radiator, and pay attention to rinse from the inside to the outside first. (6) Use a high-pressure water gun to flush the left and right wheel fenders and the drainage holes in the engine room, and remove leaves and dirt.

7) Use a high-pressure water gun to rinse the dirt or dust inside the support rod in the cabin.

Quality: Clean and dirt-free after washing.

Precautions for cleaning the engine:

1.When the engine is at high temperatures, it is necessary to prevent the engine from burning your hands.

2.When scrubbing other parts of the headbox, take care to prevent the joints and wires from scratching your hands.

3.When the engine is stopped, never open the hood.

4.Be careful when closing the hood and not too heavy.

5.Some parts of the engine must be waterproof.

Industry insiders like to say that the engine is the heart of the car, which shows that the maintenance of the engine is as important as the maintenance of the heart. It is hoped that the majority of car owners will pay attention to cleaning and maintaining the car engine and do not let the car "unpack". The above has introduced how to clean the car engine, I hope it will be helpful to everyone.

1. Protect before cleaning.

First of all, after the engine has cooled down, cover the battery with plastic sheeting to prevent damage to the electrodes by cleaning agents or water. Also need to be covered are the fuse box, ignition coil, and generator to prevent splashing. Because the smell of the detergent is pungent and long-term exposure is harmful to the human body, remember to wear a mask and gloves.

2. Remove the decorative cover.

Next, remove the engine trim cover. The engine trim cover is made of plastic, has a large area, is fastened by a snap and can be removed. Dust is most noticeable on the surface, and there is a lot of oil under the trim cover, so you have to remove it to clean the parts underneath.

3. Spray cleaning agent.

Spray the cleaning agent onto the engine parts that need to be cleaned, and don't forget to remove the trim cover. Where the oil stain is thick, spray the cleaning agent and brush it with a brush to disperse the oil quickly.

Wipe dry after minutes.

After spraying the detergent for 5 minutes, wipe it off with a towel, and if the oil does not spread out, you can wash it several times until it feels clean. You can also rinse with a high-pressure water gun, but be sure to waterproof the parts mentioned above, and then dry them with suede or a cloth with good water absorption, or blow dry them with a hair dryer.

5. Use glazing agent.

After cleaning, the engine polishing agent is used for glazing operation, and the effect is the same as the body coating, which is beautiful and practical. At this point, the engine compartment is cleaned.

1. Prepare the tools.

We know that the biggest source of pollution from a car's engine compartment is dust and mud, and to clean the engine compartment by yourself requires an engine cleaner, a brush (or a discarded toothbrush), a towel and a watering can, which are basically enough.

2. Detergent cleaning.

The engine compartment cannot be sprayed directly with water, but should be cleaned with detergent. The purpose of using detergent is to remove the oil in the engine compartment, and it is necessary to spray the detergent on each part and wash it carefully with a small brush.

3. Wipe with a wet towel

After cleaning with detergent, you can choose to wipe with a damp towel, which can effectively avoid damage to the relevant circuit caused by splashing water.

4. Drying moisture:

If you want the moisture in the cabin to dry faster, you can start the engine after wiping off the moisture, and use the heat of the engine operation to dry the moisture that adheres to the surface. Once the water has completely evaporated, the cleaning of the engine compartment is complete.

It should be supported that the engine compartment cannot be washed directly with water, and many vehicles have an explicit state in the instruction manual, if it is too dirty, it is recommended to blow it clean with a gun. Although the engine compartment components and wiring harness connections are waterproof, with the accumulation of use, the tightness is not guaranteed, and it is very risky to flush the engine compartment directly with water!

Spray the engine exterior cleaner on all parts including the engine compartment, focusing on more sludge areas, but avoid wiring and circuit boards. Wait about 2 minutes for the engine exterior cleaner to fully react with the dirt.

Use a prepared toothbrush and scrub wherever you have been sprayed with a car interior cleaner, and if the sludge is thick, use some force here without worrying about scratches (that's why you use a toothbrush).

The protective cover of the fuse box is removable, and in order to ensure the overall appearance, it can be disassembled and then cleaned. Wait about 2 minutes after washing.

Use the prepared watering can to spray all areas after washing, while paying attention to some dead spots, and then use a toothbrush to scrub together. After the washing is completed, do not wipe and dry the work, but also clean the wiring and circuit parts.

Hello! Engine cleaning includes two methods: one is to use a special cleaning agent to clean without opening the engine, generally we call it "hanging bottle", so that the cost is low, and the general maintenance shop can do it, and the cleaning effect is still good.

Another is to disassemble the engine for cleaning, so that the cleaning is more thorough, the disadvantage is that the cost is higher, and the maintenance shop with poor qualifications is not competent.

Start the car engine, check whether there is oil leakage in the inlet pipe and return pipe of the car, clean it for about 20 minutes at idle speed, and increase the throttle once before it reaches about 4 minutes, so that the carbon deposits and water in the engine can be fully discharged from the exhaust pipe during the cleaning process.

1. First open the fuel tank cover, then take out the filter cartridge inside, use the hose to pump out the fuel in the fuel tank, leaving about 10-15 cm deep, then add 80ml of ethanol gasoline to replace the cleaning agent, reinstall the filter cartridge, and then cover the fuel tank cap.

2. Disassemble the engine inlet and return pipes, and then connect the oil inlet pipe and the oil return pipe of the engine with the oil inlet pipe and the oil return pipe of the no-dismantling cleaner, and use a special interface to connect the oil inlet pipe and the oil return pipe to form a loop.

3. The owner can add fuel to the oil storage tank with no-dismantling cleaning agent according to the scale on the oil storage tank of the no-dismantling cleaning machine or according to the number of cylinders of the automobile engine, and add 100ml of ethanol gasoline to replace the cleaning agent.

4. According to different car models, the pressure should be adjusted appropriately, under normal circumstances, the EFI vehicle needs to adjust 2 to 3 pressures, and the carburetor model can be adjusted to a more appropriate pressure.

5. Start the car engine, check whether there is oil leakage in the inlet pipe and oil return pipe of the car, clean it for about 20 minutes at idle speed, and increase the throttle once before it reaches about 4 minutes, so that the carbon deposits and water in the engine can be fully discharged from the exhaust pipe during the cleaning process.

6. Disassemble the oil inlet pipe and oil return pipe of the no-dismantling cleaning machine and the car engine to restore the entire oil circuit system to normal, start the car engine, and the owner carefully check whether there is oil pipe leakage.

7. Open the fuel tank cap of the car, then take out the filter cylinder inside, insert it into the bottom of the fuel tank from the fuel tank mouth with a thin pipe, and then turn on the air pump to purge it with an air pressure of 3kg cm, so that some impurities in the fuel tank will churn up and be swept away.

8. After the impurities at the bottom of the car fuel tank are blown clean, the owner needs to discharge the gasoline in the fuel tank.

The most common, and at the same time the simplest, engine cleaning is:

Engine cylinder cleaning, this type of cleaning of new cars is generally built.

The negotiation is carried out once between 4-60,000 kilometers, after which it can be.

About 30,000 kilometers can be cleaned as appropriate.

The operation of cleaning in the cylinder is relatively simple and the most common way.

It is to add cleaning agent to the old engine oil before maintenance, and then.

Start the car and let the engine pass the reciprocating motion of the pistons autonomously.

Wash the interior of the line, and after a period of time turn off the flame according to the maintenance flow.

You can change the oil and oil grid.

There is no need to clean the engine for 10,000 kilometers of the new car, and the cleaning of the engine throttle injector is carried out every 20,000 kilometers.

And the protection of the engine can be carried out with each oil change.

There is a brake fluid steering machine.

The gearbox oil is generally changed once for 40,000 kilometers, of course, it is at this time to clean and protect.

The cleaning you do is part of the Intensive Care series.

It is more thorough and professional than regular maintenance, so it is correspondingly more expensive.

However, it is good for the service life of the entire parts and parts of the car, which is a basic process, and how much time is it.

It is still necessary to look at the working condition of the car and carry out the necessary operations according to the actual situation.

When engine oil works in a high-temperature environment, it will inevitably suffer from oxidation and pollution. Therefore, after a period of use, the engine will produce carbon deposits, oil stains, and gum. These contaminants will reduce or even block some of the engine's delicate oil circuits, so that the oil cannot properly lubricate and protect the various parts of the engine.

When the car starts, especially when it starts cold, it is easy to wear the engine because the oil cannot provide effective protection for the engine in time. In addition, the adhesion of oil sludge to the cylinder wall will also increase friction, resulting in fuel consumption. At the same time, dirty oil can cause insufficient oil pressure, which can lead to valve failure with hydraulic tappets, causing abnormal engine noise, unstable idling, and reduced engine power.

Therefore, for some cars whose engines have not been cleaned and maintained for a long time, have a long oil change cycle, and have poor road conditions, a simple oil change can no longer keep the engine interior clean, so engine cleaning is required. For normal vehicles, when driving to 45,000 kilometers, it is also necessary to clean and maintain the engine.

How to clean: Engine cleaning, which is divided into two parts: external cleaning and internal cleaning. The general steps of external cleaning are: turn off the fire; Wait for the engine to cool down; Wrap the distributor, ignition coil and other devices with plastic film to prevent water ingress; Cleaning with a special cleaning agent; After cleaning, use a hair dryer to dry the wire joints.

Internal cleaning is the key to engine cleaning. Generally, the disassembly-free cleaning method is used, which can be carried out when the oil is changed. The general steps are:

Pour the engine cleaning agent into the oil filler, mix it with the old oil, and drain the oil after idling for 20 to 30 minutes. Today's professional engine cleaners can make engine cleaning easy, and you can see the effect of increasing engine power in a short time, and you can also hear the engine sound taper.

Cleaning a car engine is a technical job, if you don't understand it, don't do it yourself, go to the car repair shop and find a professional to clean it.

How to clean a car engine? In this way, you can directly get the four S shop or get this car repair shop to clean it directly, and this kind of car beauty shop can clean the engine, so that you can clean it with money.

Is it used for car engine cleaning?

When the engine of the car is working, the temperature is usually very high, so the things attached to it will solidify after the jujube is steamed in an instant, so water, mud, dust and various oil stains will mix with each other to form a variety of dirt. First of all, to remove the dirt from the engine compartment, you can first wipe it with a damp cloth, if this can clean the engine compartment very cleanly, then do not wash it with water.

If a damp cloth doesn't clean the dirt, try a regular detergent to wipe it off. If you have tried both of the above methods and still can't wipe off the dirt, choose to clean with water.

When cleaning, wrap all parts that cannot get wet, and then use brushes, water, and detergent to remove dirt. If you encounter dirt that is difficult to remove from the vertical bottom, you need to use an engine-specific cleaner.

It is best to choose a foam cleaner because the foam stays on the surface of the dirt for a longer period of time, breaking it down and bringing it to the surface. However, these cleaners are usually chemically strong, so rinse with water for at least 10 minutes to get clean.

Precautions. 1.The first step is to remove dirt or dust, which can be removed with water.

2.Engine-specific cleaners should not be used on baking paints.

3.The aluminized water tank cover and exhaust pipe should be cleaned with a special detergent.

4.Try not to use powerful detergents and use household detergents instead.
